US Patent:

6478791, Nov 12, 2002

Filed:

Dec 23, 1999

Appl. No.:

09/470906

Inventors:

Garry L. Carter - Pleasanton CA
David C. Densow - Livermore CA
John P. Claude - San Carlos CA
Paul L. Do - San Jose CA
George A. Morrison - Foster City CA

Assignee:

SURX, Inc. - Livermore CA

International Classification:

A61B 1700

US Classification:

606 1, 606139

Abstract:

Improved devices, methods, and systems for the surgical treatment of urinary incontinence generally enhance the support provided by the natural tissues of the pelvic floor without directly applying compressive pressure against the urethra. The invention provides probes for forming plications in the endopelvic fascia that are displaced laterally on either side of the midline. These probes can impose a predetermined level of trauma to the plicated tissues so as to promote the formation of adhesions. Adhesions can maintain the enhanced support provided by the plication after reabsorption of a temporary fastener (such as a reasborbable suture, staple, or the like). The plicating probe draws the tissue inward to provide a uniform plication within a predetermined size range.

Assignee:

Solarant Medical, Inc. - Livermore CA

International Classification:

A61B 1818

US Classification:

606 28, 606 41

Abstract:

The invention provides improved devices, methods, and systems for repeatably and reliably contracting fascia and other support tissues, particularly for the treatment of urinary incontinence. Rather than relying on a surgeons ability to observe, direct, and control the selective shrinking of pelvic support tissues, a relatively large surface of a tissue contraction system is placed statically against the target tissue. Sufficient controlled energy is transmitted from the surface into the engaged tissue to contract the tissue and inhibit incontinence (or otherwise provide the desired therapeutic results).

International Classification:

A61B 18/04

US Classification:

606 34, 606 41, 606 45

Abstract:

An electrosurgical electrode assembly having a cutting device including a catheter with a proximal and distal end, and an electrode carried on the distal end of the catheter. A controller is connected to the cutting device. A data acquisition system is connected to the controller and is capable of monitoring voltage and current output. A microprocessor may also be connected to the data acquisition system for processing voltage and current data from the data acquisition system. A generator is also connected to the data acquisition system. The controller initiates movement of the electrode upon arc initiation at the electrode. Methods of using the devices herein are also disclosed.

International Classification:

A61B 18/18
A61B 10/00

US Classification:

606 41, 600564, 606 45

Abstract:

A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A pivot joint may be used to pivotally connect the distal separator end to the distal shaft portion. The distal shaft portion may comprise a distally-facing transition surface at a proximal end of the distal shaft portion. First and second energizable tissue separator elements may be used at the transition surface and the tip of the device, respectively.
